Mortality from fire & wind is increasing in Europe's forests, but what about biotic disturbances? A new, massive dataset compiled by @thlasny.bsky.social and many local experts shows a mixed picture: While wood borers increase strongly, defoliator activity generally decreases doi.org/10.1111/gcb....

Congratulations @julieedtree.bsky.social on this cutting-edge research, out today #AGUpubs!

High-resolution tree-ring data are dramatically improving our ability to estimate past climate. We’re now much closer to accurately tracking temperature changes—both today and across history!

As droughts become longer and more intense, their toll on ecosystems could be far greater than we thought. Our new paper in @science.org shows how prolonged & extreme droughts cause dramatic, cumulative losses in ecosystem productivity across the globe www.science.org/doi/10.1126/...

Rarely do I get to see seminars that truly inspire—but this one hit all the high notes! Thanks for visiting us!
Great visit to UCSB & an honor to present in the EEMB seminar series. Was fun to talk forests, fire, & resilience w/ many awesome faculty, graduate students & undergrads.

Thanks to Anderegg Lab for hosting me, esp Joe Celebrezze. Was fun to be back at my UG alma mater.

Plants cool the land through evapotranspiration, but green foliage can absorb more heat than lighter surfaces, causing warming. A study finds that in the northern hemisphere, cooling outweighs warming until the end of the growing season. In PNAS: www.pnas.org/doi/10.1073/...
